Lex

Lex is an AI-native word processor designed by writers, for writers. Rather than retrofitting AI onto an existing editor, Lex starts with a familiar Google Docs–style writing surface and embeds AI as a quiet collaborator: you can ask it to brainstorm ideas, suggest a better sentence, fix a paragraph, or fact-check a claim, all without leaving the page. Notable features include in-line AI feedback that critiques an essay the way a trusted editor would, multi-model access (Claude, GPT, and Gemini are all available from the same surface so writers can compare voices), a research mode that pulls citations and summaries while you draft, voice dictation, and clean exports to Markdown, PDF, and Word. Collaboration tools — comments, suggestions, shared docs — match Google Docs feature-for-feature, which makes Lex a credible primary writing surface rather than a brainstorming detour. Lex was built by Every (the publishing/operator team) and has become a quiet favorite among professional writers, founders, and knowledge workers.

Key capabilities at a glance: AI-native word processor with familiar Google Docs UX; Multi-model access: Claude, GPT, Gemini in one surface; Inline AI feedback that critiques your writing; Research mode with citations and summaries; Voice dictation and clean exports (Markdown, PDF, Word); Real-time collaboration with comments and suggestions.

Where Lex wins: Multi-model access from one surface is rare and genuinely useful for comparing voices; Inline 'feedback from an editor' mode is more thoughtful than typical AI rewrite buttons; Clean exports to Markdown/PDF/Word — no lock-in; Real-time collaboration on par with Google Docs; Built by people who actually publish, which shows in the editor's restraint.

Trade-offs to weigh: Pro pricing isn't transparent on the public site; Yet another writing surface to move your team to — switching cost from Google Docs is real; Research mode citations need human verification — still LLM-summarized; Limited offline support compared to native desktop editors.

Best-fit scenarios include: Long-form essay and article drafting; Founders and operators writing memos and strategy docs; Researchers drafting with inline source lookup; Replacing Google Docs as a primary writing surface.

Pricing structure: Free ($0) — Core editor with limited monthly AI credits and access to basic models. | Pro (Paid (tiers on website)) — Higher AI credit limits, access to top-tier models (Claude, GPT, Gemini), and research mode. | Teams (Custom) — Shared workspaces, SSO, and team management.
